* @add: adds a `GtkCellRenderer` to the area.
|

|
|
* @remove: removes a `GtkCellRenderer` from the area.
|
|||
|
|
* @foreach: calls the `GtkCellCallback` function on every `GtkCellRenderer` in
|
|||
|
|
* the area with the provided user data until the callback returns %TRUE.
|

|
|
* @foreach_alloc: Calls the `GtkCellAllocCallback` function on every

|||
|
|
* `GtkCellRenderer` in the area with the allocated area for the cell
|
|||
|
|
* and the provided user data until the callback returns %TRUE.
|
|||
|
|
* @event: Handle an event in the area, this is generally used to activate
|
|||
|
|
* a cell at the event location for button events but can also be used
|
|||
|
|
* to generically pass events to `GtkWidget`s drawn onto the area.
|
|||
|
|
* @snapshot: Actually snapshot the area’s cells to the specified rectangle,
|
|||
|
|
* @background_area should be correctly distributed to the cells
|
|||
|
|
* corresponding background areas.
|
|||
|
|
* @apply_attributes: Apply the cell attributes to the cells. This is
|
|||
|
|
* implemented as a signal and generally `GtkCellArea` subclasses don't
|
|||
|
|
* need to implement it since it is handled by the base class.
|
|||
|
|
* @create_context: Creates and returns a class specific `GtkCellAreaContext`
|
|||
|
|
* to store cell alignment and allocation details for a said `GtkCellArea`
|
|||
|
|
* class.
|
|||
|
|
* @copy_context: Creates a new `GtkCellAreaContext` in the same state as
|
|||
|
|
* the passed @context with any cell alignment data and allocations intact.
|
|||
|
|
* @get_request_mode: This allows an area to tell its layouting widget whether
|
|||
|
|
* it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
|
|||
|
|
* %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
|
|||
|
|
* @get_preferred_width: Calculates the minimum and natural width of the
|
|||
|
|
* areas cells with the current attributes applied while considering
|
|||
|
|
* the particular layouting details of the said `GtkCellArea`. While
|
|||
|
|
* requests are performed over a series of rows, alignments and overall
|
|||
|
|
* minimum and natural sizes should be stored in the corresponding
|
|||
|
|
* `GtkCellAreaContext`.
|
|||
|
|
* @get_preferred_height_for_width: Calculates the minimum and natural height
|
|||
|
|
* for the area if the passed @context would be allocated the given width.
|
|||
|
|
* When implementing this virtual method it is safe to assume that @context
|
|||
|
|
* has already stored the aligned cell widths for every `GtkTreeModel` row
|
|||
|
|
* that @context will be allocated for since this information was stored
|
|||
|
|
* at `GtkCellAreaClass.get_preferred_width()` time. This virtual method
|
|||
|
|
* should also store any necessary alignments of cell heights for the
|
|||
|
|
* case that the context is allocated a height.
|
|||
|
|
* @get_preferred_height: Calculates the minimum and natural height of the
|
|||
|
|
* areas cells with the current attributes applied. Essentially this is
|
|||
|
|
* the same as `GtkCellAreaClass.get_preferred_width()` only for areas
|
|||
|
|
* that are being requested as %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT.
|
|||
|
|
* @get_preferred_width_for_height: Calculates the minimum and natural width
|
|||
|
|
* for the area if the passed @context would be allocated the given
|
|||
|
|
* height. The same as `GtkCellAreaClass.get_preferred_height_for_width()`
|
|||
|
|
* only for handling requests in the %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT
|
|||
|
|
* mode.
|
|||
|
|
* @set_cell_property: This should be implemented to handle changes in child
|
|||
|
|
* cell properties for a given `GtkCellRenderer` that were previously
|
|||
|
|
* installed on the `GtkCellAreaClass` with gtk_cell_area_class_install_cell_property().
|
|||
|
|
* @get_cell_property: This should be implemented to report the values of
|
|||
|
|
* child cell properties for a given child `GtkCellRenderer`.
|
|||
|
|
* @focus: This virtual method should be implemented to navigate focus from
|
|||
|
|
* cell to cell inside the `GtkCellArea`. The `GtkCellArea` should move
|
|||
|
|
* focus from cell to cell inside the area and return %FALSE if focus
|
|||
|
|
* logically leaves the area with the following exceptions: When the
|
|||
|
|
* area contains no activatable cells, the entire area receives focus.
|
|||
|
|
* Focus should not be given to cells that are actually “focus siblings”
|
|||
|
|
* of other sibling cells (see gtk_cell_area_get_focus_from_sibling()).
|
|||
|
|
* Focus is set by calling gtk_cell_area_set_focus_cell().
|
|||
|
|
* @is_activatable: Returns whether the `GtkCellArea` can respond to
|
|||
|
|
* `GtkCellAreaClass.activate()`, usually this does not need to be
|
|||
|
|
* implemented since the base class takes care of this however it can
|
|||
|
|
* be enhanced if the `GtkCellArea` subclass can handle activation in
|
|||
|
|
* other ways than activating its `GtkCellRenderers`.
|
|||
|
|
* @activate: This is called when the layouting widget rendering the
|
|||
|
|
* `GtkCellArea` activates the focus cell (see gtk_cell_area_get_focus_cell()).
